225 Jahre UV‐Strahlung – Die Rekonstruktion des Ritter‐Experiments (1801) für Schule und Hochschule

open access: yesCHEMKON, EarlyView.
Am 22. Februar 1801 gelang Johann Wilhelm Ritter in Jena der experimentelle Nachweis einer unsichtbaren Strahlung jenseits des violetten Bereichs des sichtbaren Spektrums. Als Indikator nutzte er die photochemische Schwärzung von Hornsilber (Silberchlorid) und erbrachte damit erstmals einen indirekten experimentellen Nachweis der ultravioletten ...

Loss of POGLUT2/3‐mediated O‐glucosylation produces lung and aortic phenotypes reminiscent of fibrillin1 mutants

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Fibrillins provide a scaffold for elastic fiber formation, which enables lung recoil and aortic compliance. Abnormal fibrillin microfibrils, as in Marfan syndrome, lead to enlarged alveoli, vascular stiffening, and aneurysms. Our earlier studies suggested that fibrillin function depends on O‐glucosylation of its epidermal growth ...

ZnO‐Coated Silicon Oxide Nano‐Anode: Synergistic Enhancement of Cycling and Thermal Stability of Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Lithium‐ion battery anodes that maintain good performance and excellent stability under high temperature conditions. Silicon oxide (SiO) has great potential as a high‐capacity anode for lithium‐ion batteries, but its practical use is limited by excessive volume expansion (>200%) and rapid capacity fade, especially at high temperatures.

Organotrifluoroborate‐Driven Phase Stabilization and Defect Suppression for Wide‐Bandgap Perovskites

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A multifunctional additive, trifluoro(pyrrolidin‐1‐ium‐1‐ylmethyl) borate (PyMe‐BF3), leverages B‐F coordination and N‐H hydrogen bonding to passivate undercoordinated Pb2+, fill halide vacancies, and suppress phase segregation. Its preferential enrichment at the buried interface targets the defect‐rich region, enabling simultaneous wide‐bandgap ...
